General Fiat Stilo 5-door Engine warning light

[Bulin]

Today i was trying to look and the air bag clips under me seat and so i had not success to knock of air bag warning.
But i ended up driving the car as i was going over a ramp my engine light came on .
i turned the key of and on and it went of then i drove it again and it came back on and will not go of.
the car is struggling when driving like lack of power and engine is vibrating the car badly.
sorry about poor grammer
